Bazedoxifene acetate (WAY-140424; TSE-424) is an oral, nonsteroidal, indole-based selective estrogen-receptor modulator developed by Ligand Pharmaceuticals in collaboration with Wyeth Pharmaceuticals (NJ, USA) (now Pfizer) . It was developed using raloxifene as a template with the benzothiophene core substituted by an indole ring in order to obtain favorable effects on the skeleton and lipid metabolism with the additional improvement of a neutral effect on hot flushes and without stimulating the uterus or the breast. The drug is approved as a monotherapy for the prevention and treatment of osteoporosis and in combination with conjugated estrogens for the treatment of menopausal symptoms and prevention of osteoporosis. Bazedoxifene binds to both ERalpha and ERbeta with high affinity. Bazedoxifene acts as both a receptor agonist and/or antagonist, depending upon the cell and tissue type and target genes. Bazedoxifene decreases bone resorption and reduces biochemical markers of bone turnover to the premenopausal range. These effects on bone remodeling lead to an increase in bone mineral density (BMD), which in turn contributes to a reduction in the risk of fractures. Bazedoxifene functions primarily as an estrogen-receptor antagonist in uterine and breast tissues.

Liquiritigenin is a plant-derived flavonoid isolated from the roots of plants belonging to licorice species (Glycyrrhiza uralensis, Glycyrrhiza glabra, Glycyrrhiza inflate etc) and is available in common foods and alternative medicine. Liquiritigenin is one of the major active compounds of MF101, selective ER-beta agonist herbal extract of 22 botanical ingredients originally tested for reducing the frequency and severity of menopausal hot flashes. At sufficient concentrations, liquiritigenin is also a partial agonist of ER-alpha but has a 20-fold higher affinity for ER-beta than for ER-alpha. Several studies showed that liquiritigenin exerts cytoprotective effects against heavy metal-induced toxicity in cultured hepatocytes, has protective effects against liver injuries induced by acetaminophen and buthione sulfoximine in rats and has an anti-inflammatory effect in macrophages suggesting its potential therapeutic use for liver diseases. Liquiritigenin inhibits the activity of MAO A and B in rat brain mitochondria and displayed favorable properties as a specific transient receptor potential melastatin 3 (TRPM3) blocker. Anti-hepatocellular carcinoma effects of liquiritigenin are related to its modulation of the activations of mitogen-activated protein kinase (MAPKs) and was discovered, that this compound is a potential therapeutic agent for hepatocellular carcinoma treatment.
